WHEPPING DEVICE.

Specification of Letters Patent.

Patented May 7, 1907.

Application filed October 24,1906. Serial No. 340,396.

To all whom, it may concern.-

Be it known that I, LA FAYETTE G. DoBBs, a citizen of the United States, residing at Watertown, in the county of Codington and State of South Dakota, have invented a new and useful Whipping Device, of which the following is a specification.

This invention relates to a Whipping device intended for use more particularly in connection with such apparatus as self binding reapers, and the like, where the operators attention is given to driving the machine and to controlling the levers and other parts of the operating mechanism of the binder, so that his hands must be free for holding the reins and actuating the levers, as occasion requires, without the additional burden of carrying the whip.

The invention has for one of its objects to provide a Whip actuating mechanism which is of simple and improved construction and positive and reliable in operation.

A further object of the invention is to provide a Whipping device adapted to be driven by the mechanism of the binder and which can be thrown into and out of operation at will by the driver.

Another obj ect is to provide means whereby the whip can be adjusted readily to operate on either horse of the team as the driver desires.

A still further object resides in the provision of means whereby the stroke of the whip is gradually accelerated as it descends pppn the horse, so as to give a more effective as i.

Vith these objects in view, and others, as

will appear as the nature of the invention is better understood, the invention comprises the various novel features of construction and arrangement of parts, which will be more fully described hereinafter and set forth with particularity in the claims appended thereto.

Tn the accompanying drawing, which illustrates one of the embodiments of the invention, Figure 1 is a side elevation of the whipping mechanism shown applied to a self binding reaper. Fig. 2 is a plan view of the pivotally mounted Whip socket and adjacent parts. Fig. 3 is a front elevation of the gearing for actuating the whip with an accelerating stroke. Figs. 4 and 5 are diagrammatic views showing the gearing of Fig. 3 in different operative positions.

Corresponding parts in the several figures are indicated throughout by similar characters of reference.

While I have elected to illustrate the invention, in the present instance, as applied to a self binding reaper, I desire to have it understood that the whipping device is not necessarily limited to this class of apparatus, but that it may be used on other ap aratus Where it is desired to relieve the wor i of the driver or where the driver maybe seated at a point more or less remote from the horses.

Referring to the drawing, 1 designates that portion of the frame of the binder supporting the apron 2, and the platform 3 supporting the operators or drivers seat 4. The construction of the binder is immaterial as far as the invention is concerned, and only suflicient is shown to illustrate the connection of. the whipping mechanism therewith. The apron 2 is driven by the roller 5 on the shaft 6 journaled at the upper end of the frame 1 and provided at one end with the pinion 7 meshing with the power' mechanism of the binder.

Located above the frame 1 and apron 2 is a horizontal shaft 8 ournaled on the bearing frames 9. At one end of the shaft 8 is located a gear 10 meshing with the apron roller pinion 7, so as to receive power from the driving mechanism of the binder. This shaft, which forms a part4 of the whipping mechanism, is adapted to be operatively connected to the binder by means of a clutch device comprising a toothed collar 11 feathered on the shaft and adapted to engage, bymeans of its teeth, the teeth on the gear wheel 10, which wheel is adapted to run loose when the clutch is open. The collar 11 is adapted to be shifted by the foot of the operator, and for this purpose a treadle 12 is provided on the platform 3 and connected with the lever 13 by a pitman 14, the lever 13 being fulcrumed on the right hand bearing frame Q and provided with a pin 15 that engages in a peripheral groove 16 in the collar. The clutch is normally held open by a spring 17 connected therewith and a leaf spring 1S under the treadle. Thus, when the driver wishes to use the whip device, the treadle 12 must be depressed against the tension of the spring 1S so as to shift the toothed collar 11 to the right, against the tension of the spring 17. By releasing the treadle, the whipping device is automatically thrown out of operation.

At the left hand side of the frame 1 is supported the swinging whip carrying arm 19 which hinges on the pintle 20 formed integral or otherwise suitably secured to the adjacent bearing frame 9. The arm 19 is a suitable casting having an eye or sleeve portion 21 that fits over the pintle, and at the left hand extremity is a whip socket 22 pivoted at 23 so as to swing in a vertical plane on a hori- Zonta] axis. The socket 22 carries a crank arm 24 that has a split ring portion 25 that encompasses the socket and is adjustably held thereon by means of the thumb screw 26 clamping the ends of the split ring portion together. By this means, the crank arm can be adjusted nearer to or farther from the pivotal center 23 so as to make the stroke of the whip light or heavy, that is to say, by adjusting the arm upwardly, the stroke will be made light, and by adjusting it downwardly, the stroke will be made heavy. The arm 24 is connected with a revolving crank 125 by means of the pitman 126, the crank 125 receiving motion from the shaft 8 through a suitable gearing. In order to permit the whip carrying arm to swing, without impairing the operative relation between the shaft 8 and crank mechanism for actuating the whip socket, the shaft 8 is made in two sections connected by a universal joint 27 located in line with the pintle 20, or axis of Swing, of the said arm. The arm 19 is provided with a bearing 28 for the section 29 of the shaft 8.

The gearing for transmitting motion from the shaft 8 to the crank 125 is of special construction in order that each stroke of the whip can be effected with an accelerating movement and that an idle interval can be produced between each stroke, so that the strokes will be properly timed and the driver given an opportunity to release his foot between the strokes. The gearing thus comprises a gear wheel 30 having the radial teeth 31 extending around a portion of the periphery only, so as to form a mutilated gear. Meshing with the teeth 31 is the pinion 32 secured to the shaft 33 of the crank arm 125. By this arrangement, the crank arm 125 is rotated once during one revolution of the wheel 30 and a relatively long idle period intervenes between each time the mutilated gear wheel rotates the crank 125. The pinion 32 is eccentrically mounted on the shaft 33 and the teeth 31 of the mutilated gear are waved, as shown in Figs. 4 and 5, so as to properly mesh with the eccentrically mounted pinion. Thel object of this arrangement is to cause the crank 125 to revolvequicker at one por tion of a revolution than at the diametrically l opposite portion, and the parts between the crank 1.25 and whip socket are so arranged that the downward stroke of the whip will be made with a gradually increasing speed, so that a strong, sharp lash will be given to the horse. The upward stroke of the whip will be at a gradually decreasing speed, so that the parts will have comparatively little in ertia to overcome at the end of the upward stroke. On the inner end of the piniony 32 is a cylindrical stud 34 which has a chordal surface 35. The stud 34 is arranged in line with the axis of the shaft 33, andthe flat surface 35 is adapted to engage with the smooth annular face 36 on the gear 30 when the teeth 31 are not in mesh with the pinion. words, the surfaces 35 and 36 constitute a locking device whereby the whip is held upe right and the parts in their operative positions. To adjust the arm 19 so as to bring the whip 37 into the proper position to strike a given horse, a shipper rod 38 is provided that is connected with the arm 19 by a hinge connection with the bracket 39. The free end of the rod 38 is formed into a handhold 39 which is adjacent the drivers seat, and the rod is locked in any desired position by the teeth 40 and toothed arm 41 supported on the platform 3. 4 i

From the foregoing description, taken in connection with the accompanying drawing, the operation will be understood as now briefly explained. As shown in Fig. 1, the parts are in their normal position, or, in other words, the whipping device is idle. When the driver wishes to use the whip, he presses the treadle 12, so as to throw in the clutch. The shaft 8 is then rotated, so that the crank 125 will be moved through one revolution, so as to cause the whip to strike the horse and return to its upright position.

In Fig. 4, the pinion 32 is shown as just starting on its whipping stroke, the teeth' 31 being'considered as moving in the direction indicated by the arrow. The speed of the pinion will gradually increase from the end 42 until the crest 43 is reached., which corresponds to the end of the whipping stroke. As the mutilated gear 31. continues to move, the pinion revolves through the other half of its revolution at a gradually decreasing speed, until the end 44 of the gear disengages. At the time the gear disengages from the pinion, the fiat surface 35 of the stud 34 will come into engagement with the, flat face 36, as shown in Fig. 5, the said flat face being represented by a broken line in diagram. The gear 30 will continue to revolve without actuating the grip until the teeth 31 are again brought into engagement with the pinion. lf the operator desires to strike the horse again, he will keep his foot on the treadle during the idle period of the pinion, so that the operation will be repeated. If, however, one strike is sufficient, the operator will release the treadle at some point during the engagement of the surfaces 35 and 36, so that the whip will be held stationary in its upright position. When the driver desires to strike the other horse, the shipper In other lOO rod 38 is disengaged and then moved longitudinally until the front end of the arm 19 is behind the desired horse. The shipper rod is then again locked and the treadle 12 de- ,f

pressed for actuating the whip.
